HPC base capacity: 4 stations
Conventional capacity: up to 23 stations
Options: PCM-300, PCM-900 or PCM-1600
PCM-300 adds three conventional stations and expands an HPC base controller from 4 to 7 stations
PCM-900 adds nine stations but requires a PCM-300 in the first expansion slot for a 16-station HPC
PCM-1600 adds sixteen stations but requires a PCM-300 in the first slot for a 23-station HPC
Nine and sixteen-station modules fit the upper expansion positions rather than the first expansion slot
Power Lock secures and energizes installed modules inside the HPC cabinet
Controller automatically recognizes the installed conventional station capacity after proper installation
Each module adds terminals for standard 24 VAC valve wiring
PCM modules are compatible with HPC and supported Pro-C generations
Pro-C model and date-code compatibility must be verified before purchasing a PCM-1600
EZ Decoder two-wire expansion uses a separate PC-DM Decoder Module and is not included with these PCM options

Description

The Hunter HPC Zone Expansion Kit adds conventionally wired irrigation stations to a compatible Hunter HPC or Pro-C® controller. An HPC begins with four stations. Install a PCM-300 to expand it to seven stations. To reach 16 stations, use a PCM-300 in the first expansion slot plus a PCM-900 in the upper slots. To reach 23 stations, use a PCM-300 plus a PCM-1600. The 9 and 16-station modules do not replace the required PCM-300 in the first expansion slot.

Choose the module by the controller’s current configuration and required final station count, not simply by the number printed on the module. These modules add 24 VAC valve terminals for conventional field wiring and are sold individually. They do not provide EZ Decoder two-wire expansion, which requires the separate PC-DM Decoder Module and compatible decoders. HPC recognizes installed modules after they are locked into place. Pro-C compatibility varies by controller generation and date code, especially for PCM-1600, so verify the controller label and module-compatibility chart before ordering.

Great option if you don't want to buy a more expensive box

Worked perfectly as an expansion from my Hunter sprinkler box. I upgraded to a Hunter wifi unit from an old school box. Needed to buy two of these and they plugged right in and the box recognized them automatically and I took care of the rest from the app. Super easy connectivity and control from the app.

Hunter sprinkler system

Worked perfectly I recommend this product

Perfect fit

This module was a perfect fit for my PRO-C irrigation controller. It was very easy to install.

Works well

Got this for our watering system, it has been working well since installing. It does the job well.

Hunter PCM1600

works as it should!

Good but pricey

Quick and easy install and works fine. A bit pricey for something very simple though.

Solved my problem caused by the same product?

I guess the one running the backyard zones in our new house failed, and the extra one in the control box was bad too... This new one made everything function again. I don't know what the other failures say about durability though... They are priced close enough to the knock offs that you might as well buy the real thing.

As described

As described.. easy install worked perfect

Easy installation.

3 zones were not working. Was not getting power from a module in my control box. I ordered this one to replace it. It was easy. Just removed zone wires from the old one, slide the unlock switch and unplug it. Plug new one in, slide lock switch, and install wires in same slots as the old one. Issue fixed and saved a great deal of money by not having to call a sprinkler repair company.

Easy to install

Great add on for more watering stations.

Excellent experience

Fixed my issue. Rapid delivery. Painless process.

It worked.

Perfect match to the old part.Fixed the problem.

Working great

Put it in a few months back and I’ve had no issues with the zone it controls.

Fixed my sprinkler system

When my sprinkler system quit working, I did some googling and deduced that this was the problem. The price was expensive but cheaper than any other place online so I bought it. Fixed!

Quality item that works great!

Purchased this expansion module and I was very happy with the item. Easy to install and works great..

as advertised

worked exactly as advertised- super easy to replace and install <2min

Worked perfectly

Prompt delivery and worked perfectly

Solved my problem. Recommended

Fit right in the control box and solved my problem. Now, all the zones in my sprinklers work

Works as intended

Very easy to install, works as expected.

Worked Perfectly and Installation was Easy

Worked perfectly. I watched a video on how to replace them on YouTube. With NO electrical experience, I was easily able to swap these out and my sprinklers were back up an running.

High quality, solidly built

Plug and play. Yes, the whole controller is designed to get more money from you. These are really just a plug with wire terminals. Everything else is already included in the controller. It would have been cheaper for them to make the controller with all the zones possible up front. Fewer parts, inventory, potential failure points, etc. That said, this part works without issues.

It works

Fits exactly as original.

Works as advertised.

Expensive but works as advertised.

I Didn't Need It

The module works fine. It was on me that my old module is the same as the new module.

Work as advertised

For an unknown reason, maybe a power surge, my sprinkler controller was dead when I tried to start for the season. Had power, all settings were working, timer worked etc. Just no response when I turned it to run. Replacing both of these modules solved the problem. Easy to replace, simple instructions. System started working immediately.

Direct replacement

Direct replacement for defective unit

Fits and Works Great for My Hunter Pro-C

Fits and works great. This replacement part design seems to be made for a few models of Hunter controllers, but it fit and is working fine. For my controller this part didn't have the locking tab, but it fits so snuggly that shouldn't be a problem. It also, has an "extra" terminal on the top that my controller doesn't need. Plugged right in and is working are required.

1 day delivery of an OEM replacement part not available locally

Quick 1 day delivery of an OEM part I couldn’t buy locally. Easy installation and the product fixed my sprinkler controller issues. Would buy again

Great

Perfect to get me to the 15 zones I needed

Great

Seller very responsive. I purchased this to replace a 19 year old module. Attached 2 wires, push module into slot. Works. Done! Im Happy.

Works great!

Great packaging and the correct product!!

Sprinkler station replacement Hunter

Arrived as described. Secured and sealed! Worked well.

three zones not going on repair

Was estimated $300 repair from the local irrigation system repair to replace this part took me 5 minutes and a one screwdriver and cost of part saved over $200

Frequently Asked Questions

Can the Hunter HPC Zone Expansion Kit add more irrigation zones to my controller?

Yes. Compatible expansion modules add station capacity to supported Hunter modular controllers.

Which Hunter controllers work with the HPC Zone Expansion Kit?

The expansion modules are intended for compatible Hunter HPC and Pro-C modular controller installations.

What is the difference between the 3, 9 and 16-station expansion modules?

Each adds a different number of additional irrigation stations. Choose the module based on the controller configuration and desired total station count.

Does an HPC expansion module work as a standalone irrigation controller?

No. It must be installed in a compatible Hunter modular controller.

Can I add more zones to an existing Hunter HPC without replacing the controller?

Yes. That is one of the primary benefits of the HPC modular design.
